Some time ago I had some discussions with my fellow chippers on these fractional chips. Mr. Sahara was going through the archives today and wanted to post these up for further discussion. I believe the chip on the far right is another version of the .50 Rivera hot stamp and is not pictured in the chip guide. I have a few of these in the collection. Your comments are welcome. If it is determined to be please submit to the chip guide. I posted the group of four together and 2 others for close ups. At first glance one may think it was a heavy stamping but if you look close the spacing and thickness of the number 5. Also the ball at the end of the 5 and with the cent sign seems different.
